Abstract (en)

[origin: WO0127743A1] A method for determining if writes to a memory subpage are directed to target instructions which have been translated to host instructions in a computer which translates instructions from a target instruction set to a host instruction set, including steps of detecting a write to a memory subpage storing target instructions which have been translated to host instructions, detecting whether a sub-area of the memory page to which the write is addressed stores target instructions which have been translated, and invalidating host instructions translated from addressed target instructions.
